 A number of the CAN and power connectors in the system use a Weidmuller LSF series wire-to-board connector. There are a few things to keep in mind when using this connector for best results:
 
 - Wire should be 16 AWG (1.5 :math:`mm^2`) to 24 AWG (0.25 :math:`mm^2`) (consult rules to verify required gauge for power wiring)
